Natural rock panel, natural rock veneer panel and panel support apparatus

Abstract

An architectural finish element operable to be placed adjacent similar architectural finish elements to form a finished surface on an architectural structure includes a body formed of a rock-based composite material comprising a low density solid particle additive, a plurality of unitary real stone veneer elements bonded to the body in courses extending in a first direction and in a random non-repetitive pattern, the real stone veneer elements having respective face surfaces generally lying in a plane to form an overall face surface of the architectural finish element. The low density solid particle additive is provided in an amount suitable to cause the architectural finish element to have a density of between about 10 to 15 pounds per square foot. The architectural finishing element may be mounted by mounting a portion of a body of at least one dual architectural finish element support to a surface of an architectural structure.

AI Technical Summary

Benefits of technology

The invention provides an architectural finishing method that allows for the attachment of finish elements to a building surface. The method involves using a support body with two holders to hold the top and bottom edges of two finish elements in a way that their surfaces are coplanar. The support body absorbs the forces between the finish elements and the building surface, reducing any stress on the finish elements. Ultimately, this method ensures that the finish elements are securely attached to the building, and the overall appearance of the building is enhanced.

Problems solved by technology

Installation of this type of element is time-consuming, and such elements can be susceptible to release from the surface due to thermal expansion and contraction, which can loosen mortar adhesion systems that secure such elements to an architectural structure for example.

Further, such individually secured stone elements are often joined by mortar joints having thicknesses of about ⅜ inches or more, and such mortar joints may have an undesirable appearance.

Some inventors have overcome the mortar adhesion problem by cutting grooves into the individual stone elements and using a support clip that cooperates with the groove to support the individual stone element, but this tends to secure the stone elements rather rigidly to the surface of the architectural structure, which can still be a problem due to wind loading and seismic loading.

Forces due to these conditions can result in displacement of the individual stone elements from the clips, resulting in release of one of more of the stone elements from the structure.

Generally, individual stone elements are not aggregated together into unitary collections to form an architectural finish element because the stone elements themselves are generally relatively heavy such that any unitary collection of stone elements is generally too heavy to be lifted by a single person and would be too heavy to meet many building codes.

To reduce weight, individual stone elements may sometimes be secured to a foam backing for example, but the foam can deform over time if subjected to point loading and can be susceptible to ultraviolet radiation degradation and can present challenges for fire proofing.

Artificially formed surfaces comprised of concrete painted and molded to look like a dry-stacked arrangement of individual stone elements have been used on foam to form building blocks but are still too heavy and therefore not suitable for cladding a building.

Patio and walkway surfaces have been paved by masonry panels comprising a reinforced series of masonry elements such as stone or brick pavers bound together by a cement or mortar-like material, but these too are too heavy for cladding an architectural structure.
